Question

Hello i´m trying to set info from a post method into a variable that sets a session named name the value that the user input. I get the following error:

Notice: Undefined index: name in F:\xampp\htdocs\Impossible game\index.php on line 18

This is line 18: $session = $_POST[‘name’];

<form action="ms1.php" method="POST">
Name <input type="text" name="name">
<input type="Submit" value="Begin">
</form>
<?php
$session = $_POST['name']; 
session_start();
$_SESSION['name'] = $session;

the previous error is gone and now this appears

Notice: Undefined variable: session in F:\xampp\htdocs\Impossible game\index.php on line 23 below is line 23

 $_SESSION['name'] = $session;

Below the code is commented but untested. Please let me know if their are any issues.

    <?php
    if(isset($_POST['name'])){           //if the post has been set
        $session = $_POST['name'];       // Store the session in the variable
        session_start();
        $_SESSION['name'] = $session;    // Store the name in a session for later use
header("location:index.php");    // Redirect the user     ##UPDATE##
    }   else    {
        //if post has not been set, show the form
    ?>
    <form action="ms1.php" method="POST">
    Name <input type="text" name="name">
    <input type="Submit" value="Begin">
    </form>
    <?php
    }
